본 발명은 캐니스터 에어필터의 구조에 관한 것으로서, 보다 상세하게는 필터엘리먼트의 고정구조에 관한 기술이다.The present invention relates to a structure of a canister air filter, and more particularly, to a technique for fixing a filter element.

캐니스터는 연료탱크에서 발생되는 연료증발가스를 포집하고 있다가, 엔진이 적절한 조건이 되면 포집하고 있던 연료증발가스를 엔진으로 보내어 연소시킬 수 있도록 함으로써, 연료증발가스의 대기 누출을 방지하도록 한다.The canister captures the fuel evaporation gas generated from the fuel tank and, when the engine is in a proper condition, sends the captured fuel evaporation gas to the engine for combustion, thereby preventing the leakage of fuel evaporation gas into the air.

상기와 같이 포집하고 있던 연료증발가스를 엔진으로 보낼 때는 대기중의 공기가 캐니스터를 통과하면서 연료증발가스를 엔진의 흡기계로 유도하게 되는데, 이때 캐니스터로 유입되는 공기는 캐니스터 에어필터에 의해 여과되도록 되어 있다.When the fuel evaporation gas collected as described above is sent to the engine, the atmospheric air passes through the canister to guide the fuel evaporation gas to the intake of the engine, and the air flowing into the canister is filtered by the canister air filter. It is.

상기 캐니스터 에어필터에 내장된 필터엘리먼트가 지나치게 오염되는 경우에는 통기저항이 증가되어, 캐니스터와 연결되어 있는 연료탱크 등에 엔진으로부터 제공되는 과도한 부압이 작용할 수 있다.If the filter element embedded in the canister air filter is excessively contaminated, the ventilation resistance is increased, and the excessive negative pressure provided from the engine to the fuel tank connected to the canister may act.

본 발명은 캐니스터 에어필터에 내장된 필터엘리먼트가 오염된 정도에 따라서 저절로 오염물질을 이탈시킬 수 있도록 함으로써, 캐니스터 에어필터의 통기저항을 일정 수준 이하로 유지할 수 있도록 하고, 연료탱크 및 기타 인접부품의 손상을 방지할 수 있도록 한 캐니스터 에어필터 구조를 제공함에 그 목적이 있다.According to the present invention, the filter element embedded in the canister air filter may spontaneously remove contaminants depending on the degree of contamination, thereby maintaining the ventilation resistance of the canister air filter at a predetermined level or less. It is an object of the present invention to provide a canister air filter structure that can prevent damage.

상기한 바와 같은 목적을 달성하기 위한 본 발명 캐니스터 에어필터 구조는 The canister air filter structure of the present invention for achieving the above object is

상기 하우징의 내부에서 상기 유입구와 상기 유출구 사이를 각각 독립된 공간으로 분할하고, 상기 유입구와 상기 유출구에 대해 각각 수직한 상태의 공기유입면과 공기유출면을 가지도록 상기 하우징의 내부에 직립한 상태로 설치된 필터엘리먼트 및; In the interior of the housing, the inlet and the outlet are divided into separate spaces, and the air inlet and the air outlet in a state perpendicular to the inlet and the outlet, respectively, in an upright state inside the housing.

을 포함하여 구성된 것을 특징으로 한다.Characterized in that configured to include.

이하, 첨부된 도면을 참조하여 본 발명의 바람직한 실시예를 설명하면 다음과 같다.Hereinafter, exemplary embodiments of the present invention will be described with reference to the accompanying drawings.

도 1은 본 발명의 캐니스터 에어필터가 장착된 상태를 설명한 도면으로서, 연료탱크(1)에 캐니스터(3)가 연결되어 있고, 상기 캐니스터(3)에는 본원의 요지인 캐니스터 에어필터(5)가 연결되어 캐니스터(3)에 대기중의 공기가 유입될 수 있도록 하고, 상기 캐니스터(3)는 엔진흡기계로 연료증발가스를 퍼지시킬 수 있도록 되어 있다.1 is a view illustrating a state in which a canister air filter of the present invention is mounted, and a canister 3 is connected to a fuel tank 1, and the canister air filter 5, which is a subject matter of the present application, is connected to the canister 3. Connected to allow the air in the atmosphere to flow into the canister (3), the canister (3) is capable of purging the fuel evaporation gas by the engine intake machine.

도 2를 참조하면, 본 발명 실시예는 외기의 유입과 유출이 이루어지는 중공몸체의 하우징(7)과; 상기 하우징(7) 내에서 공기유입면(9)에 수직한 방향으로 움직일 수 있도록 설치된 필터엘리먼트(11)와; 상기 필터엘리먼트(11)의 움직임을 제한하는 운동제한수단을 포함한 구성이다.2, the embodiment of the present invention and the housing of the hollow body 7 is made of the inlet and outlet of the outside air; A filter element (11) installed in the housing (7) to move in a direction perpendicular to the air inlet surface (9); It is configured to include a motion limiting means for limiting the movement of the filter element (11).

상기 공기유입면(9)이란 공기가 유입되는 필터엘리먼트(11)의 면을 말한다.The air inflow surface 9 refers to the surface of the filter element 11 into which air is introduced.

상기 하우징(7)은 대기측과 연결되는 유입구(13)와 캐니스터(3)에 연결되는 유출구(15)가 각각 구비되어 있으며, 상기 유입구(13)와 유출구(15)를 사이를 가로지르도록 상기 필터엘리먼트(11)가 설치되어 있다.The housing 7 is provided with an inlet 13 connected to the atmosphere side and an outlet 15 connected to the canister 3, respectively, so as to intersect the inlet 13 and the outlet 15 therebetween. The filter element 11 is provided.

상기 필터엘리먼트(11)는 그 공기유입면(9) 및 공기유출면(17)의 가장자리가 프레임(19)에 고정되고, 그 외의 부분에는 필터엘리먼트(11)의 운동을 구속하는 별도의 구조가 없어서, 필터엘리먼트(11)의 가운데 부분은 필터엘리먼트(11)를 통과하는 공기의 유동방향을 따라서 움직일 수 있는 구조이다.The filter element 11 has an air inlet surface 9 and an edge of the air outlet surface 17 fixed to the frame 19, and the other part has a separate structure that restrains the movement of the filter element 11. Therefore, the center portion of the filter element 11 is a structure that can move along the flow direction of air passing through the filter element (11).

상기 프레임(19)은 상기 하우징(7)의 내부에 장착될 수 있도록 되어 있다. 즉, 상기 필터엘리먼트(11)가 프레임(19)에 미리 고정되어 모듈화된 상태에서, 상기 프레임(19)을 하우징(7)의 내부에 고정하여, 캐니스터 에어필터(5)가 완성되도록 한 구성이다.The frame 19 is adapted to be mounted inside the housing 7. That is, in the state in which the filter element 11 is fixed to the frame 19 and modularized, the frame 19 is fixed to the inside of the housing 7 so that the canister air filter 5 is completed. .

본 실시예에서, 상기 운동제한수단은 상기 필터엘리먼트(11)의 공기유입면(9)과 공기유출면(17) 중앙을 각각 가로지르도록 설치된 판스프링(21)들로 이루어져 있다.In the present embodiment, the movement limiting means is composed of leaf springs 21 installed to cross the center of the air inlet surface 9 and the air outlet surface 17 of the filter element 11, respectively.

상기 판스프링(21)들의 양단은 각각 상기 프레임(19)에 마련된 삽입홈(23)에 삽입되어 고정되도록 함으로써, 프레임(19)과 필터엘리먼트(11) 및 상기 판스프링(21)들이 하나의 모듈로서 상기 하우징(7)의 내부에 결합될 수 있는 구조를 채택하였다.Both ends of the leaf springs 21 are inserted into and fixed to the insertion grooves 23 provided in the frame 19, so that the frame 19, the filter element 11, and the leaf springs 21 are one module. As a structure it can be coupled to the interior of the housing (7).

물론, 상기 판스프링(21)은 그 양단을 상기 하우징(7)에 고정하도록 하는 방식으로 설치할 수도 있다. Of course, the leaf spring 21 may be installed in such a manner that both ends thereof are fixed to the housing 7.

상기한 바와 같이 구성된 캐니스터 에어필터(5)는 캐니스터(3)의 퍼지시에 캐니스터 에어필터(5)로 유입되는 공기중에 포함된 이물질이 상기 필터엘리먼트(11)에 부착되어, 통기저항이 커지면, 필터엘리먼트(11)가 움직이면서 저절로 부착된 이물질을 필터엘리먼트(11)로부터 탈락시키도록 한다.When the canister air filter 5 configured as described above has foreign substances contained in the air flowing into the canister air filter 5 at the time of purging the canister 3 attached to the filter element 11 and the ventilation resistance is large, As the filter element 11 moves, the foreign substances attached by itself are removed from the filter element 11.

즉, 이물질의 부착으로 필터엘리먼트(11)의 통기저항이 커지면, 캐니스터(3) 내부의 압력 변화에 따라, 상기 필터엘리먼트(11)는 필터엘리먼트(11)의 공기유입면(9)에 수직한 방향으로 움직이고, 이와 같은 움직임은 상기 판스프링(21)들에 의해 적절한 범위로 제한되며, 그 움직임에 의해 필터엘리먼트(11)에 부착된 이물질이 떨어지도록 하는 것이다.That is, when the ventilation resistance of the filter element 11 increases due to the attachment of foreign matter, the filter element 11 is perpendicular to the air inflow surface 9 of the filter element 11 according to the pressure change in the canister 3. Moving in the direction, such movement is limited to the appropriate range by the leaf springs 21, so that foreign matter attached to the filter element 11 falls by the movement.

상기와 같이 떨어진 이물질은 차량의 주행중 발생하는 진동에 의해 상기 하우징(7)의 유입구(13)를 통해 외부로 배출되게 된다.The foreign matter dropped as described above is discharged to the outside through the inlet 13 of the housing 7 by the vibration generated during the running of the vehicle.

물론, 상기 필터엘리먼트(11)의 움직임 정도는 상기 필터엘리먼트(11)의 공기유입면(9)측과 공기유출면(17)측의 압력 차이와 상기 판스프링(21)들의 탄성력에 의해 결정되므로, 실험에 의하여 적절한 판스프링(21)의 탄성력을 설정하면 된다.Of course, the degree of movement of the filter element 11 is determined by the pressure difference between the air inlet surface 9 side and the air outlet surface 17 side of the filter element 11 and the elastic force of the leaf springs 21. What is necessary is just to set the elastic force of the appropriate leaf spring 21 by experiment.

따라서, 필터엘리먼트(11)는 과도한 오염이 미연에 방지되어, 적절한 통기저항의 수준을 지속적으로 유지할 수 있도록 하므로, 연료탱크(1)나, 기타 캐니스터(3) 내부에 형성되는 압력의 영향을 받게 되는 인접부품들의 변형이나 파손 등이 방지된다.Therefore, the filter element 11 is prevented from excessive contamination, so that it is possible to continuously maintain the appropriate level of aeration resistance, thereby being affected by the pressure generated inside the fuel tank 1 or the other canister 3. Deformation or damage of adjacent parts to be prevented.

이상과 같이 본 발명에 의하면, 캐니스터 에어필터에 내장된 필터엘리먼트가 오염된 정도에 따라서 저절로 오염물질을 이탈시킬 수 있도록 함으로써, 캐니스터 에어필터의 통기저항을 일정 수준 이하로 유지할 수 있도록 하고, 연료탱크 및 기타 인접부품의 손상을 방지할 수 있도록 한다. As described above, according to the present invention, by allowing the filter element embedded in the canister air filter to be freed of contaminants on its own, the ventilation resistance of the canister air filter can be maintained at a predetermined level or less, and the fuel tank And other adjacent parts to prevent damage.
